Need help wrapping

MIOS programming (C)
1

I know it’s not chiristmas… :stuck_out_tongue:

QBAS did me some superb code for a 9 by 18 matrix. However, I want to add other function to the code (as one does), but QBAS is an assembly man, and I’m not.

Am I right in saying that the main.asm file in the assembly version should become the mios_wrapper.asm in the sdcc skeleton, and just copy all associated files into the mios_wrapper folder  OR am I just as stupid as George Bush? ::slight_smile:

Project nearly finished, so photos etc on the way…

Mark.

George Bush isn’t stupid and neither are you… But your guess was about as right as he is a good speaker  ;D

You’ll need to wrap the ASM that qbas sorted out into the main.c, using techniques like those at the How to mix C and ASM wiki page, or include the ASM file in your C project, using techniques like the using assembler in C - question about _ in front of macro names post :slight_smile:

Feel free to post/PM/email me for a hand.

erk-- a lot of asm- lost, totallty lost.

In the ucaaps there are great example blocks of code, like how to send cc values when a pot has been moved. Is there an ASM version of this anywhere. All I want to do is assign 20 slide pots set values, and never have to touch them again.

AAny ideas?

Try this mate. As stolen from mb64 like a cowardly pirate, yargh.

;; --------------------------------------------------------------------------
;;  This function is called by MIOS when a pot has been moved
;;  Input:
;;    o Pot number in WREG and MIOS_PARAMETER1
;;    o LSB value in MIOS_PARAMETER2
;;    o MSB value in MIOS_PARAMETER3
;; --------------------------------------------------------------------------
USER_AIN_NotifyChange
	;; convert 10-bit value to 7-bit value
	rrf	MIOS_PARAMETER3, F	; value / 2
	rrf	MIOS_PARAMETER2, F
	rrf	MIOS_PARAMETER3, F	; value / 2
	rrf	MIOS_PARAMETER2, F
	rrf	MIOS_PARAMETER3, F	; value / 2
	rrf	MIOS_PARAMETER2, F
	bcf	MIOS_PARAMETER2, 7	; clear 8th bit

	;; now: pot number in MIOS_PARAMETER1
	;; 7-bit value in MIOS_PARAMETER2

	;; CC Ch 0
	movlw 0xB0
	call        MIOS_MIDI_TxBufferPut

	;; CC# = Pot#
	movf MIOS_PARAMETER1, W
	call        MIOS_MIDI_TxBufferPut

	;; CC Value = Pot Value
	movf MIOS_PARAMETER2, W
	call        MIOS_MIDI_TxBufferPut

Cheers Captain Hook. That would be the very thing!!! ;D
